MEASIIRINGQPUMP ATTACHMENT.

.Afpiieatin 'fried-May i5, isis. serial No. 97,554.

This invention pertains to measuring and vdispensing apparatus and relates more particularly to yan attachment vfor' ineasuriii, pumps for delivering .predetermined quantif ties of liquid from a bulk supply.

l Such apparatus is nou7 extensively used in garages and similar 'establishments for the purpose ofdispensing gasolene to motorists. As usually arranged the complete apparatus comprises a storage tank for gasolene, which,

in accordance with the laws of n 'iost localities, is usually buried in the -grounch anda measuring. pump situatedy on the'surfaceof the ground or floor and adapted, when 'properly' adjusted`a`nd operated, to draw measured lquantities of gasolene fromthe tank andy to deli-ver the same, though a discharge pipe or hose, directly into the fuel tank of the vehicle.' .Ast-he mechanism of .the pump is usually' inclosed within a casing, and as the gasolene is drawnfrom a'hidden source'and is delivered directly to the fuel tank without being seen, there is no way in which the customerv can positively determine' whether or not the pump is in perfect working order and is properly adjusted and operated. He is therefore forced to rely, to a certain extent,'iipon thecare and honesty of' the. dealer. It is possible for unscrupulous i dealers to take advantageA ofthese condi tionslto cheat. the. purchaser, while, on the.

other hand, many careful'and honest dealers are embarrased by lack of confidence on the part of suspicious customers. Automatic measuring pumps are extremely convenient .45 and lhighly eflic'ieiit for the purposes above' mentioned, and are constantly' coming into '-the iasolene'to run by gravity into the more general'use, andit is therefore very desirable, 'for -the protection of-both parties to everysale of gasolene, that means be pro- 50. vided whereby the customer can quickly and 'easily convince'liiinself that he is receiving Athe exact quantity paid for.

The presentinvention accordingly has for' its general object the provision of an attach-l ment for measuring pumps, for dispensing measured quantities of liquid, which is Specification of Letters Patent.'

reference being had thereinto the Patented 'Nov'. E72S, I

readily applicable to existing y-pumps of this character, ,as usuallyconstructed and' ai.d1 ranged, which will, notl interfere with the .normal operation ofthe pump, but will serve '30 to 'check and visually indicate'to .the custoiner the quantities of liquid measured and 1 deliveredby the pump.

. The foregoing and other more particular g objects of the invention, together with means' l5 whereby the same may be carried into effect. vwill best be understood from vthe following description of 'one forni and :iipplication'v thereof illustrated in the 4accompanying drawings; It will be understood, however, 70 Vthat theJ particular embodiment of the' invention described and shown has been chosen for illustrative purposes merely, and'v that vsaid invention, as defined vb v the claims hereunto appended, may beotherwise piac- -tised without departing from the spirit and scope thereof. Y

The measuring pump lshown iii Fig. 1

.is of a ,common type fainilir to thoseskilled in the art, and the pumping and measuringl mechanism thereof is not illustrated in de-l tail as specifically it forms no part of the 90,

' present invention andisfitselfwell known.l

Generally speaking, said piiiiip comprises a] ,ca-sing 1 2, which houses the mechanism for drawing` measured .quantities of liquidfrom aburied storage tank (not shown) said casing beingsurinouiitedfby va hollow upright or lamp'post The pumping'and measuringmechanism is operated by a crank or handle- 14.tlie quantities being indicated von a rack scaleli, and the liquid being delive-red through a discharge pipe; 16 which, in order to secure a `suihcient head to enable' and outwardly beneath the hood 17 at the lower end'fthereof. In accordance with the fic,

suitablegraduations 3l y The measuring vessel 19 is supported and. vinclosed b v a casing comprising a top member 20, a bottom member 21,. au intermediatey member 2'2. an upright 223 .(see Figs. 3 and l) connecting' the-members 20, 21, and :22, an upright 2l connecting` the members 21 and and fitting the exterior of` the pump upright 13. and a pair of doors .25 hinged to the upright Q3 and provided with latches or locks 2G cooperating with the upright 2l.

' Said casing is attached to the exterior of the pump upright 13 by means of clamps 2T, carried by the members 21 and '22, embracing the upright 1.3', and secured in position thereaboutby means of bolts 22S. The members 21 and 22 are provided with substantially central openings to receive lower and upper nipples 29 and 30 onV the vessel 19, to the latter of which is connected the discharge pipelG, and to the former of which is connected a delivery pipe or hose 31 provided at its end with a delivcrynozzle 32 and controlled b v a valve 33 (see Fig. 2) located immediately adjacent the nipple '29 at the bottom of the casing. The doors are arranged at oppositesides of the. -asing, and when closed serve completely to inclose, protect, and conce-al the measuring vessel, but when open expose said vessel at opposite sides, 4permitting the customer or other observer to see. completely through the same.

ln use the doors 25 are opened, the valve @3 closed, and the measuring pumpoperated in the usual manner to dischargefa. predetermined quantity of gasolene through thepipe`16. Said gasolene, however, instead of being delivered directly tothe fuel tank, is discharged into the measuring vessel 19, where its volume may be readily observed and checked. Thereafter the 'alve 33 is opened and the gasolene allowed to run from the vessel 19 through the delivery hose 31 to the fuel tank in the usual manner.

It will, of course, be understood that the measuring vessel 19 is not intended to take the place of the measuring mechanism of fthe pump; but is merely designed to indition, serve as acheck upon each other.

Having thus described my invention, I claim:-

` 1. An attachment for measuring` pumps of the type-'comprising an upright or post and an upwardly .directed discharge pipe supported by said post, said attachment comprising a casing having means for securing the same to said post, ay graduated measuring vessel within said casing and adapted to receive `liquid from said discharge pipe, and avalve controlled delivery pipe yleading from'sa'id vessel and casing.

2. An -attachment for measuring pumps comprising a casing provided with means for securing the same to the pump upright, a transparent measuring vessel withiirsaid casing and arranged to receive'the dis lharge from the pump, and a valve controlled dclivery pipe leading from the bottom of said vessel and casing,l said casing being provided with doors for closing the opposite sides thereof but adapted to be opened 'toj exposethe opposite sides of saidwf'essel.

An apparatus of the character dc wholly independent of one another in operaa scribed, comprising a measuring force pump having a hollow post extending' upwardly therefrom and provided with a lateral opening and an upwardly directed discharge pipe within said post and extending through said opening, said pump being adapted to force measured quantities of liquid through said discharge pipe, a graduated measuring vessel secured to the exterior of said post and with which said discharge pipe communicates7 anda valve` controlled delivery pipe leading from said vessel.

In testimony whereof I alix my signature.
